I have an electronic timer set to switch my tank lights on at 12pm and turn off at 10pm. The main reason is so I can enjoy my fish when I come home at night. The tank also gets some indirect sunlight from 6am onwards. Is 8hours of darkness a day enough night time for tropical fish or should I readjust my timer?

cheers
 
Do you have live plants in the tank? I would say 8 hours of tank lighting is generally enough for the fish and plants depending on the wattage of light being used.
